The area of a square field is 0.5 hectare. Its diagonal would be
(a)50 m
(b)$50 \sqrt{2} \mathrm{m}$
(c)100 m
(d)250 m
Answer
Explanation
Area $=0.5$ hectare $=(0.5 \times 10000) \mathrm{m}^{2}=5000 \mathrm{m}^{2}$. $$\therefore \quad \frac{1}{2}(\text { diagonal })^{2}=5000 \Rightarrow \text { diagonal }=\sqrt{10000}=100 \mathrm{m} .$$
